Application fllecl'l'iily 28,

To all fw hom t may concern Be it known that I, ROBERTAT. MEYER, a

citizen 'of the United States, residinggat Canton, in the county of'Stark and State of" Ohio, have invented a new and useful Suction Separator, of which the followingis a specification.

This invention relates to improvements in suction'` separators, the object being to con` struct a separator of this class in which the maximum amount of agitationl can be given to the material being separated, thus caus' ing it to bemore readily acted upoii by the current of air drawn through the separating cylinders. y

Another object is to construct a separator of this class with double rotating cylinders through which the airy suctiony is drawn, thus agitating the material being separated constantly, which4 permits the air being sucked through the saidcylindersvto more quickly separate the material and enabling the machine to separate a greater volume of material in a given length of time.

lVith these objects in view the inventionconsists inthe novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appendv ed claim, it being understood that various changes in the form, proportions, size and minor details ofl construction may be made within the 'scope of the appendedclaim, without departing from the spiritor sacricing any of the advantages ofthe inven` tion. l

In the drawings: Figure 1 is a side elevation of my separator with the horizontal bars upon therne'ar' side broken away toL disclose the krotating cylinders and mechanism therefor. l

-Fig. 2 is an enlarged longitudinal sec-y tional view through the j feed opening and center terminals of the rotating cylinders.

Fig. 3 is a front elevation of my machine.'v Fig. 4 is a section through one of thejcylinders at the point 4&4, on Figl.

Similar numerals of reference indicate corresponding parts` throughout the severall figures of the drawings.y f

Atl I have indicated generally'a suitable frame formed ofy channel bars or similar` material and properly vbraced r`tocarry the mechanism of my' separator. A fan shaft 2 upon which is mounted afan carried in a v fan casing 4 is adapted to bedriven by a belt 1919. Serialrll'o.A 313,845:

vleads to a discharge door 11 located in the extreme lower cornerof the chamber. VThe chamber 8 is preferably made lofsheet metal and' connected to vone end "of the framework 1 in any convenient and well known manner. 1 Mounted at the inside upper cors ner of the chamber'S is a casting 12 with a substantially right angular passage there-y through, one en'd of which passage opensk into the said chamberB. Securedto oppo sltely extending lugs 14 upon the said'l castingis a supportmember 15, thel other end;

of which is secured to a casting 16, Which is mounted to slide between the guide barsl? y at the front end ofthe frame. A forwardly projecting flangey 18 preferably formed iirtegralfwithythe casting 16 'atjits upper edge lias'aA centrally located aperturetherethrough inwhich is mounted to rotate one end of the adjusting lscrew 19, which adjusting screw extends upwardlyy and through the end cross member of `the frame and has threaded thereon-a hand wheel'20, by the rotationvof'k which the" adjusting screw can be raised or lowered to raise or lower the casting16. At the lower end ofl the casting 16 is a` forwardly jprojecting flange 21, which extends between the guide bars 17 and isdesigned to act asa guide for the said castingwhen the same is raised orlowereda4 The front end of the casting 12 formsa bearing for the upper end of the cylinderV 22, the lower yendk of` which carries a collar '24, the, said col lar havingv an annularL flange 25, which tits about fan annularflan'ge 26 t formed uponv La v` castingy 27" ."mountedy upon -the* 'supportbar 15; 1 annularjlange28 substan' tially similar to thev flange 261extends'from` f the opposite sidezof the casting-27 andjisde signed.' to form` agbearingfor vthe` annularl flangeA 29;.formedE preferably integral with the.collar .30 ,1said 'collar 'lbeingattached:

tothe second cylinifler, 31, thel'owerfend'ofv the second cylinder 31 beingmountedfto rotate within 'the-casting'lG; I f Afneck 32 extends upwar castingf27 and receives the lower end of the dly from the feed pipe 34 which leads from a hopper 35 mounted upon the top of the frame work. A lug 36 formed upon the .casting 12 constitutes one bearing for a drive shaft 37, the other bearing for the said shaft" being formed in the lug 38 upon `the casting 16, and carried by the said shaft and adapted to rotate therewith arepinions 39 and 40 which mesh with gears 41 and 42respectively, the gear 41 beingsecuredabo'ut the cylinder 22 and the `gear 42 being secured about the cylinder31. `The upper end of the shaft 37 has secured thereto a beveled pinion 44 which meshes with a second beveled pinion 45 keyed to a shaft 46, which shaft is mounted in suitable bearings secured to the frame work.k The shaft 46 is rotated from any desired source of power preferably by belt and pulley, but it will be understood that any kind of gear may be used to transmit lpower to said shaft. The rotation of the shaft 46 will cause the shaft 37 to be rotated byl the meshing' of the beveled gears 44 and 45. rIhe rotation of the shaft 37 will therefore causethe cylinders 22 and 31 to be rotated by the meshing of the pinions 39 and 40 with the gears 41 and 42, respectively. Located in the suction pipe is a sliding valve 50, which is arranged to be operated through the rod51, thescrew threaded end of which carries a hand wheel 52. A substantially similar rod 54` having a hand wheel 55npon its threaded forward` end is designed to operate a feed regulator `56 located in the feed pipe 34 leading from the hopper 35 to the casting 27. lWithin the cylinders 22 and 31 and extending longitudinally therethrough is a plurality of agitator vanes 57 which are designed to, tumble the material being separated to thus enable the air sucked through to more efficiently act upon theiparticles of matter. n

The operation of myv devicewill be as follows: Vire will assume that the separator isgto be employed for the purpose of separating metal from ore. Thejfan within the casing 4 is set inmotion to create a suction through the pipe 6 and chamber 8 and by virtue of the passage inthe casting 12 connecting the cylinders with the said chamber 8, the suction created by the fan will draw air through thefcylinders 22 and 31, from the` lower or open end ofthe cylinder 31 thus forming a suctionl the entire length of both cylinders. The pulverized ore con'- taining particles of the metal isnow fedy .in through `the hopper 35 and descends through the feed Vpipe34 into the casting 27 through the neck 32gthereof. The-hand wheel52 isnow rotated to adjust the sliding valve 50V in the suction pipeG to drawv the exact amount of airnecessary to create the naa-.8,671

proper suction through the rotating cylinders 22 and 31 to suck the particles of rock upwardly and through the cylinder 22. The particles of metal mixed with the said pulf verized rock being of greater specific gravity cylinder 22 and are kept constantly agitated4 by being carried upwardly upon the vanes 57 as the cylinder 22 rotates and falling by gravity as the surface of the vanes upon which they are carried is tilted downwardly. The particles of rock are thus constantly being carried up one side of the cylinder and dropped 'out into the airv current, eventually arriving at the upper end of the cylinder and passing through the passage inthe casting 12 and thence falling into the chamber 8. The baffle plate 9 in the chamber will force the suction to travel downwardly at this point toward the inclined bottolnlO ofthe chamber 3, and as the particles of rockvare drawn into the chamber 8 from the exit of the casting 12 they will be sucked down and slide from the inclined surface 1() outwardly and through the exit door 11. It is obvious that when ore of a different character is to be separated the valve 50 can be adjusted to admit of a greater or less suction force as the case may require to properly suck the particles of rock from the particles of metal. It will also be understood that my separator is adapted to be used for a variety of other purposes than `separating ore, such for instance as separating seeds or the like.

I-Iaving fully described my invention what I cla-im as new and desire to secure by Letters Patent, is:

In a separator of the character described, a framle, a casting supported upon said frame having an inclined passage there through and oppositely disposed, inclined flanges on its outer faces, a cylinder mounted to rotate within said frame, one end of said cylinder being journaled upon one of said oppositely extending anges, a second cylinder mounted to rotate within said frame and one of the ends ofthe said second cylinder being journaled to rotate upon the other of said oppositely extending flanges, both of said cylinders communicating through the inclined vpassage in the said casting.

In testimony that I claim the above, I have hereunto subscribed my name. v
